Switching Power Modules

Our switching power supplies include universal input capability and a variety of output options, as well as high-performance EMI input filters. Encapsulated models are available, as well as enclosed open frame, Din Rail, PC card, or chassis mount with screw terminals.

With more than half a century of power-supply experience, Daburn guarantees the Polytron Devices line of high-quality power modules, all of which meet UL’s strict safety standards. We offer many power modules designed specifically for medical applications.

More than 20 categories of switching power modules are available, as follows:

Universal Input

5 Watt Universal Input - Single and dual output; short-circuit protection; overload protection; efficiency of up to 80 per cent.

5 Watt Universal Input, Extra Small Package - Measures only 1″ by 1″ and encapsulated in a plastic case. Up to 85 per cent efficiency; short-circuit, overload, and overvoltage protection in applications up to 5 Watts.

With short circuit and overload protection, our UIL5 series of AC-DC converters feature high efficiency up to 80%, universal input of 90-264 Vac and a 2 year warranty. This series also meets all UL60950-1 and IEC60950-1 safety standards.

With a universal input range and high efficiency up to 92%, our 65-watt MUI65 series of AC-DC converters for medical applications has an operating temperature range of -25 to 80°C, low leakage current under 75µA and a built-in EMI class A filter.
